(Cl. 20G- 57) A40mm.

This invention relates to a dispensing carton having a hinged cover formed from-an integral .blank of cardboard and the 1ike. More specically, thisinvention relates to a dispensing carton for containing a roll of waxed paper from which the paper is dispensed in web form and torn oil. in suitable lengths as needed.

Generally speaking, the present invention contemplates a carton construction for dispensing or removing any article contained thereinwhich can be grasped by the ngers by opening a hingedtively long curved cut score line having extend--v ing therefrom at each end a series of alternately scored and cut scorelines of the same construe-- tion as disclosed in copending application Serial No. 390,846, led April 23, 1941, Patent No.

i 2,303,253. The hinge disclosed in this application is an improvement of said previous construction.

vided with an inverted U-shaped cut line G. The cover isprovided with acut score line 'i which forms a tongue'porti'on that .is insertable through the cutscore line 6 into locking engagement as illustrated in Figure 1, thereby locking the cover when the carton is not in use.

The important feature of the present invenv tion residesin providing a hinge I2 for the cover of a novel construction which consists in forming the. hinge with arelatively long cut score 'line having at each end a series of alternate cut and vOther further details of the invention will be T apparent from the following specication and ap- Dended drawing.

Referring to the drawing:

Figure 1 is a perspective view of the dispensing carton,

Figure 2 is a perspective view o f the carton t showing the cover open and the endof a 'rib Vof' paper projecting therefrom,

Figure 3 is a transverse sectional view taken on' y lines 3--3 of Figure 1, v

Figure 4 is a transverse sectional view taken on' 1ines I-I of Figure 2, and

n, lengths sc as to decrease the length of the creased creased portions which are -connected toA each other. Referring' to -Figures- 1 and 2the hinge is provided with a relatively long curved cut line 20 .which is concavely curved toward the free edge of the cover il and having at each end a seriesv fof spaced semiLcircular, curvilinear, triangular, or

other suitably contoured cut portions indicated by numeral I5, so that an area or tongue portion is' outlined extending beyond the hinge line defined by the straight creased score lines -as shown. in Figures 2 and 4. These cutportions'are connected by the spaced creased score lines Il which in the conventional hinge would be aY continuous score line. Each of cut lines i5 intersects the creased lines It along convergent lines and atan acute angle to the creased lines so as to form cut tongue portions extending beyond the creased lines, whereby uponhinging the cover open the fibers of the. carton will be instantly separated without substantial frictional engagement at the cut portions.- The alternate cut and creased portions of the hinge may be of any desired ratio of portion of the hinge.

In the previous construction of the carton disclosed in Patent No. 2,303,253 it was found that a Acertain amount of bulging of the cover occurred ,adjacent themiddle portion of the hinge which Figure 5 is a transverse sectional view taken on lines 5-5 of Figure 2.

Referring to the drawing, the carton l0 is preferably made from a single integral blank of cardboard and the like which is suitably cut,

scored and glued to provide a front wall i3, a rear wall 2, end walls 3, a bottom wall 5 and a top panel I.' A cover il is integrally hinged to the top panel 4 along the hinge designated by numeral I2. The cover may `he provided with a suitable cutting blade 9 afllxed to the'v free edge thereof for facilitating tearing the free end of a web 20 from a roll of paper contained within the carton. The front wall of the'carton may be proprevented easy opening of the cover by a simple manual manipulation, especially when a relatively long carton is involved of about 12 inches or more. By providing the relatively long curved cut 2lA inv approximately the middle portion of the hinge this undesirable bulging is prevented.v

Furthermore, by concavely curving this cut line 2B toward the free edge of the cover, the bers' ci the carton will instantly separate as Vsoon asV the cover is hinged open without any frictional engagement of the fibers at this cut line. The series of alternate cut and creased score lines at each end oi the curved cut line ensure further .Y easy hinging of the cover.` Preferably it is advantageous to have the curved cut line 2li extent about one-t-third'of the total hinge line length T orf-ical A at the medial portion of the hinge and to have the series of alternate cut and score lines at each end oi' the cut line extend about one-third each of the total hinge line.

According to the present construction the total length of the creased score portion on which hinging of the cover takes place isgreatly reduced so that the resistance to iiexing of the carton stock is greatly reduced, thereby providing greater ilexibility in hingrlg the cover. Furthermore, the present hinge construction permits the opened cover upon release to fall back readily into closed position as compared with the previous full line creased hinge which after opening resists closing because the fibers at the hinge must be reversely bent to their former position.

Various modifications may be made in actual carton constructions utilizing the present concept. The invention is not limited to any specic contour of the cut and creased portions of the hinge line. For example, the cut line .20 may be curved in convex relation to the free end o! the cover or it may be a straight cut line. The cut lines l5 may also be positioned in alternating reversed position in relation to the hinge.

It is to be understood that the hinge construction is not necessarily limited to the speciiic car- A ton construction herein disclosed. It may be utilized on any type of cartonconstruction having a hinged cover therefor. The cover, for example,

may be integrally hinged to any portion of an open ended container such as to the front or rear walls thereof, but the principle of hinged construction is utilized in a similar relation as in the specific embodiment herein disclosed. It is, therefore, intended to claim the invention herein disclosed as broadly as defined in the appended claims.

I claim:

1. A dispensing carton comprising a blank suitsaidI cut lines intersecting said creased lines along convergent lines and at an acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines, and a relatively long cut line connecting said series of semi-circular cuts and creased score lines, whereby upon hinging said cover open the fibers of said blank will be' instantly separated without substantial frictional engagement at the cut portions.

2. A dispensing carton comprising a blank suitably scored and cut to provide a front, rear, botvtom, end and top panels, said top panel having an lines along convergent linesand at an acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines, and a relatively long cut line connecting said series Iof semi-circular cuts and creased score lines, said cut line being concavely curved toward the free edge of said cover, whereby upon hinging said cover open the iibers of said blank will be instantly separated without substantial frictional engagement at the cut portions.

3. A dispensing carton comprising a blank suitably scored and cut to provide a front, rear, bottom, end and top panels, said top panel having an integral portion hinged along a substantially longitudinal line extending from one end of the panel to the other, said portion functioning as a cover portion, said hinge comprising regularly spaced continuous cut and creased score lines extending at each end of said hinge, said cut lines intersecting said creased linesalong convergent lines and at an acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines and a relatively long cut lineconnectlng said series of cut and creased score lines, whereby upon hinging said cover open the fibers of said blank will be instantly separated without substantial frictional engagement at the cut portions.

4. A dispensing carton comprising a blank suitably scored and cut to provide a front, rear, bottom, end and top panels, said top panel having an integral portion .hinged along a longitudinal line extending from one end of the panel to the other, said portion functioning as a cover portion, said hinge comprising a curved cut line extending at its medial portion and a regularly spaced continuous cut and creased score' line extending at each end of said curved cut line, said cut lines intersecting said creased lines along convergent lines and at an acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines whereby upon hinging said cover open the fibers of said blank will be instantly separated without substantialirictional engagement at the cut portions.
